This technique is based on the electrical interconnections. For the offshore wind farms which are located between 80 and 150 km, HVDC transmission is preferred over HVAC (high‐voltage alternating current). At present, this is an expensive technique; however, with the help of invention in the offshore installations and component techniques, its cost can be reduced in future. This technique comes with an advantage i.e. installation of a wind farm in a further offshore region which has rich wind resources. In future, this technique can lead to higher annual production of energy with less planning. Further this technology opens new doors for the regions where near‐shore developments are not possible (IRENA 2016). With the invention of direct current nodes in upcoming time, a multi‐nodal network can be built which is required for integration of this technique. With point‐to‐point grid connections used on few projects in European waters, commercialization of this technique is ongoing.
